First, have you tried a hard reset? There's a reset button hidden under the silver faceplate. If that doesn't help, and you do need a new battery, here goes...

Garmin did not design these with the intention that users could replace the batteries. However, if you're handy with a soldering iron and like to tinker, it's not too daunting a task. Rather than describe it here, I'll refer you to previous posts for the Garmin C330, which is physically identical. Good luck!.http://www.fixya.com/support/t118686-replace_battery_garmin_streetpoilot

Remove the battery out and put back in after 5 minutes to reset it., check also that the in car power cable is working, and the Garmin is not drained. Tru to connect it to power outlet if you have an adapter

Ummmmm "Low battery"....... not too hard to figure out. You need to charge it for several hours. If the battery is low it WILL go out on you and during that time, the battery may recover enough to come on briefly then go off again. Please charge your battery!

Hi - I have a Garmin GPS 2 plus unit which is around 10 years old. I haven't used it for about 2 years. Initally it powered up and eventually found satellites. I switched it on the following day and it will not power up. I have changed batteries but nothing works - tried a master reset but agin nothing - it appears to be dead ?

I followed the instructions of the Online manual for the Garmin Street Pilot c-340, I removed the faceplate of the Street Pilot and then using my thumb pressed down on the reset button. I then pressed the power on button on the side of the device- the screen lit up, I then plugged one end of the USB cable into my computer and the other end into the device. The information on the screen of the device indicated the Lithium Battery was charging properly.

I strongly recommend you to get it repaired if it is inder warranty because once you break the seal you will loose your warranty service.And since it is a sealed unit to take it apart you will need some special itype of nstruments which i don't think are available anywhere.

it would be strange for the lithium ion battery to be dead so soon. what have you done to charge it up? there are ways to kick start the batterys but i need to know a little history on what has occured up to now.
